Drilling & Completion News

Chevron subsidiary Unocal East China Sea has begun natural gas production from the first stage of the Chuandongbei Project in the Sichuan Basin of southwest China. Chuandongbei is one of the largest onshore gas projects developed by an international oil company and a national oil company in China.

Drilling & Completion Tech Digest

Rice University’s Integrated Systems and Circuits (RISC) laboratory has developed a new generation of microchips, approximately the size of a grain of sand, that travels downhole through fracturing fluids to plot the cracks and pores through which oil and gas move to the surface. Activated by electromagnetic signals sent from an aboveground transceiver, the microchips return real-time data to create high-resolution maps of reservoirs and formations formed by hydraulic fracturing.

Technology champions build up business case for MPD adoption while advancing automation, training

Although managed pressure drilling (MPD) continues to gain traction across the industry, it remains incumbent upon service providers and technology champions to build and prove a business case for MPD. This remains challenging due to the nature of the technology. One of its key benefits is minimizing or eliminating kicks and losses. However, proving that something didn’t happen can be difficult. “How do you quantify non-events? How do you quantify something that didn’t happen?” asked Per Christian Stenshorne, EC-Drill Product Line Manager for Enhanced Drilling.

Data acquisition capabilities, durability enhanced in new crop of coiled-tubing, intervention tools

The need to keep pace with the increasingly long laterals that operators are drilling remains a driver for R&D efforts around well intervention and coiled tubing (CT). However, in the current price environment, that innovation must be coupled with the ability to lower costs. New CT and intervention technologies appear to be achieving such cost reductions by increasing equipment durability, which results in fewer trips out for replacement. In addition, more real-time data collection is being used to make real-time adjustments to maximize efficiency.

After mechanization and automation, industry now looks to robotics

In the oilfield’s steady advance toward a largely robotic-driven drill floor, the profound influence of inter-industry technology transfer is undeniable. As demonstrated during the development of robotic technologies for repetitive and hazardous rig floor activities, robots employed in outside industrial settings provide sound baselines for adaption to meet drilling requirements.

From the President: As drilling contractors’ association, IADC will focus on listening to, responding to members’ needs

These are trying times for our industry. Last year was a difficult year, and this year’s forecast is equally as challenging. We have seen the effects of the depressed market reflected in the reduction of rig counts and companies who have shuttered their operations. People are comparing this downturn to the one of the mid-1980s, a time we all hoped never to revisit.

Competition for rig work ratchets up in Asia Pacific

As oil prices fell to less than $30/bbl earlier this year, the associated reduction in rig demand severely stressed drilling contractors worldwide. The Asia Pacific was no exception. “It has been relatively quiet,” said Yun Yun Teo, IHS Petrodata’s Principal Analyst for Rigs, Asia Pacific. “I don’t think we are going to see that 2016 will be much of an improvement over 2015. In fact, it will probably be worse.” For example, although operators in the Asia Pacific normally send out multiple new rig tenders during the winter budget season, this time around drilling contractors saw “only a handful,” Ms Teo said.
